Janet Carter2000Overlying surficial deposits and absent areas for Minnekahta Limestone in the Black
Hills area, South DakotaVersion 1.0, April 13, 2000mapUSGS Open-File ReportUSGS OFR00-471Reston, VAU.S. Geological Surveyhttp://water.usgs.gov/lookup/getspatial?ofr00471_mnktsurfThis data set describes areas where the Minnekahta Limestone
is directly overlain by surficial deposits, as well as those
areas where the Minnekahta Limestone is absent in the Black
Hills area, South Dakota.
Data describing where the Minnekahta Limestone is directly
overlain by surficial deposits and areas where the formation
is absent were used in the production of structure-contour
maps for the top of the Minnekahta Limestone (mnktscon). This
data set was created as part of the Black Hills Hydrology
Study (BHHS). The BHHS is a long-term investigation that was
initiated in 1990 as a cooperative effort between the
U.S. Geological Survey (USGS), the South Dakota Department of
Environment and Natural Resources (DENR), and the West Dakota
Water Development District. West Dakota represents various
local and county cooperators. The purpose of the study is to
assess the quantity, quality, and distribution of surface and
ground water in the Black Hills area of western South Dakota
(Driscoll, 1992). The study area includes parts of Butte,
Custer, Fall River, Lawrence, Meade, and Pennington counties
in South Dakota.
Reviews_Applied_to_Data:
This electronic report was subjected to the same review
standard that applies to all U.S. Geological Survey
reports. Reviewers were asked to check the topological
consistency, tolerances, attribute frequencies and statistics,
projection, and geographic extent. The reviewers checked the
metadata and a_readme.1st files for completeness and accuracy.
Related_Spatial_and_Tabular_Data_Sets:
Geologic structure contours for the top of the Minnekahta
Limestone (mnktscon), and data set of wells with geologic
information (mnktswpt) for the Minnekahta Limestone. Also,
surficial hydrogeology in the Black Hills study area
(hydrogeo).

Polygon topology present.This data set consists of surficial deposits which directly
overlie the Minnekahta Limestone, as well as areas where the
formation is absent or outcrops.
Paper plots at 1:100,000 scale were overlaid on the original
mylar sheet and outcrop areas and surficial deposits were
compared.

polygons on this mylar map.
The outcrop areas for the Minnekahta Limestone were plotted
on mylar and overlaid on a paper copy of the alluvial
deposits in the study area. The outcrop areas and alluvial
deposits were taken from the digital data set
(hydrogeo). Areas where the Minnekahta Limestone was
directly overlain by alluvial deposits were determined, and
contacts were drawn accordingly. The resulting arcs were
then digitized in ARC/INFO and polygon topology was created
using the BUILD command. Attributes were then created using
the ADDITEM command in ARC. Areas where the formation is
absent was determined by the occurrence of an outcrop of an
older formation or igneous intrusion. Polygons were then
assigned a label of 'surficial', 'outcrop', or 'absent' for
the attribute item TYPE.

AREA- Internal number for the area of the polygon
PERIMETER- Internal number for the perimeter of the polygon
MNKTSURF#- Internal sequence number (i.e. the record
number) of the polygon in the ARC file
MNKTSURF-ID- User-assigned feature ID
UNIT#- User assigned value. Polygons representing
outcrop areas were given a unit# value of 12
and surficial, absent, and subsurface areas
were give a unit# value of 0 for the Minnekahta
Limestone.
TYPE- User assigned item defining polygon
type. Polygons were assigned values of
'surficial', 'absent', 'outcrop', or 'subsurface'
in order to distinguish polygon types for the
construction of structure-contour maps.
